SpellBinder is a simple, ugly Ace2 mod that creates a GUI for the new SetBindingItem, SetBindingSpell, and SetBindingMacro functions. Simply put, it allows you to bind stuff to keys without taking up an actionbar slot.
To summon the window, use /spellbind, or set a key binding in the bindings menu.
* Click on a button on the left, then select or enter something to bind a key to.
* Click on the "Click to Set" button, then enter a key combination
* Check that the spell, item or macro name is correct, check that the key combination is correct, then click "Set Key". That's it!
